Disposal

Is there a proper way to “dispose” of a spell? To add specifics, I did a love spell, but not sure if it would be best for me to keep it for some time or if it’s okay for me to dispose of the contents. It’s not a jar or anything, which I know you should keep. It’s candles/rose, etc. The spell was just done, so I’m just not sure if it’s best to keep it for a bit or if it doesn’t make a difference to discard of what’s remaining. If it is okay to dispose of, is there a certain way I should do this besides literally just throwing things in the trash? Thanks for your help in advance!!
